BACKGROUND Advances in nebulizer design have produced both ultrasonic nebulizers and devices based on a vibrating mesh (vibrating mesh nebulizers), which are expected to enhance the efficiency of aerosol drug therapy. The aim of this study was to compare 4 different nebulizers, of 3 different types, in an in vitro model using albuterol delivery and physical characteristics as benchmarks. METH...

In response to concerns over excessive discarding from Australian recreational round traps (with four funnel entrances) used to target giant mud crabs, Scylla serrata, an experiment was done to assess the independent and cumulative utility of paired, bottom-located horizontal escape gaps (46×120 mm) and increasing mesh size (from 51 to 101 mm). Compared to conventional traps comprising 51-mm me...

BACKGROUND Reconstruction of large-size abdominal wall defect (AWDs) is a huge challenge faced in current surgical practice. In this study, we aimed to evaluate the effectiveness and safety of biodegradable poly-p-dioxanone (PDO) mesh for reconstructing large-size AWDs in an experimental canine model. METHODS Eighteen experimental canines were randomly and equally divided into three groups, n...

In this paper, the role of molecular diffusion in mobilization of waterflood residual oil is examined. A moving mesh method is applied to solve the moving interface problem of residual oil blobs swelling by Co2 diffusion through a blocking water phase. The results of this modeling are compared with experimental results of a 2D glass micromodel experiment. Although, the solution method is applie...

Finite Elements in Analysis and Design ()-This paper gives a status on anisotropic mesh gradation. We present two 3D anisotropic formulations of mesh gradation. The metric at each point defines a well-graded smooth continuous metric field over the domain. The mesh gradation then consists in taking into account at each point the strongest size constraint given by all these continuous metric fiel...

This paper provides the preliminary result in our experiments to automatically assign MeSH terms to MEDLINE abstracts. Every year about 100,000 documents are added to MEDLINE, index terms are assigned by hand to each document from a controlled vocabulary called MeSH. This is necessarily time consuming and may lead to inconsistent indexing due to the large size of MeSH. Our purpose is to explore...

We present an example where Ruppert’s refinement algorithm for quality 2D Delaunay mesh generation runs in time quadratic in the size of the output mesh. For any n > 1, input and output mesh sizes of our example are Θ(n), the bounding box dimensions are 1×Θ(n), and the algorithm running time is Θ(n). Because Θ(n) is a theoretical upper bound on the running time of Ruppert’s refinement algorithm...

In injection moulding processes such as Resin Transfer Moulding (RTM) for example, numerical simulations are usually performed with a fixed mesh , on which the displacement of the flow front is predicted by the numerical algorithm. During the injection , special physical phenomena occur on the front , such as capillary effects inside the fibre tows or heat transfer when the fluid is injected at...

In this paper, we present a feature-aware SPH method for the concurrent and automated isotropic unstructured mesh generation. Two additional objectives are achieved with proposed compared to original SPH-based generator (Fu et al., 2019). First, feature boundary correction term is introduced address issue of incomplete kernel support at vicinity. The generation curves, surfaces volumes can be h...

Tension-free vaginal mesh (TVM) surgery is a common and minimally invasive procedure for pelvic organ prolapses. Since commercial kits are not readily available in Japan, we have planned tailor-made mesh by information of each patient before every TVM surgery. The aim of this report is to inform methods to design mesh for individual patients with pelvic organ prolapses. We also investigated the...
